Does anybody understand this chart. I am sure it is easy, but forsome reason I am not getting it. It says to mix the stuff with 1 gallon of water. If I have a 10 gallon res then do I put the one gallon of water with nutes plus 9 gallons of water or do I put that mixture in for every gallon that is in the system. I have also read you should only put 1/4 what the chart says. is that true? Can anybody explain it in way better detail for me if somebody has the time. I just bought this package of nutrients in the kit.
